Radiochemical studies of state of lanthanum microamounts in water solution

Sorption of radioactive lanthanum by titanium phosphate at static and dynamical conditions was studied. Sorption coefficients of lanthanum and some other elements (143Ce, 97Zr, 99Mo,133I ,92Sr) were determined by means of γ-spectrometry. The microquantities of lanthanum are observed to be sorbed better than macroquantities which is explained by the ability of Ti to form coordination compounds with oxygen-containing ligands of multivalent element hydroxocomplexes.
